PARKER派克比例流量閥，派克比例流量閥

派克PARKER比例流量閥組作用是設(shè)定流量，自動平衡閥組作用是維持流量恒定。系統(tǒng)流體的工作壓力為P1，手動調(diào)節(jié)閥的前后壓力分別為P2、P3。當(dāng)手動調(diào)節(jié)閥調(diào)到某一位置時，即人為確定了“設(shè)定流量”Kv即手動調(diào)節(jié)閥的流量系數(shù)，流量G=Kv(P2-P3)1/2，Kv為，Kv設(shè)定后，只要P2－P3不變，則流量G不變。當(dāng)系統(tǒng)流量增大時，(P2—P3)的實(shí)際值超過了允許的給定值，此時通過感壓膜和彈簧作用使自動調(diào)節(jié)閥組自動關(guān)小，直至流量重新維持到設(shè)定流量，反之亦然。
